“…For soybeans to demonstrate their full productive potential, it needs approximately 800 mm well distributed throughout its cycle (Carvalho et al, 2013;Zanon et al, 2018). On this occasion, rainfall was less than the needs with seasonality in the distribution of water supply throughout the cycle, with deficits coinciding with flowering and grain filling (Schaparini et al, 2020).…”

This study aimed to assess genetic dissimilarity and based on the qualitative and quantitative characteristics of 52 soybean cultivars grown in the Northwest Region of the state of Rio Grande do Sul. The experiment was conducted at the Center for Research and Agronomic Results of the Missions (CEPRAM). The experimental design used was randomized blocks with treatments arranged in four replications. Soybean qualitative attributes were measured, being the maturity group, flower color, pod color, seed shape, tegument color, anthocyanin pigmentation in the hypocotyl, pubescence color, pubescence density, hilum color, seed brightness and biotechnological event. Together, quantitative attributes were measured in ten plants per experimental unit, such as yield, number of pods per plant, number of grains per plant, grain mass per plant and thousand seed mass. The most productive cultivars were P95R90 IPRO, BMX Raio IPRO, NS 5445 IPRO, P95R30 IPRO, P95Y02 IPRO, TMG 7058 IPRO and DM 5958 IPRO. Yield correlates positively with the number of pods, number of grains, grain mass and thousand seed mass. The dendrogram for the quantitative characteristics and the decision tree showed that the formation of the groups and the grain yield were determined mainly by the grain mass and the thousand seed mass. Among the components of variance and genetic parameters, the variables thousand grain mass, grain mass and yield are influenced by 59%, 32% and 29% respectively by genetic effects.

Soybean crop yield is affected in the absence of favorable conditions for its complete development, and one of the most limiting factors is the water availability throughout the crop cycle. Therefore, the objective of this study was to evaluate the behavior of three soybean genotypes, in two sowing dates, during two harvests, in the city of Rio Verde, Stat of Goiás. Four experiments were carried out in a randomized block design, with four replicates in the 2018/2019 and 2019/2020 harvests. The variables analyzed in the experiment were plant height at maturity, days to maturity, and grain yield. The water balance in the soil considered the water storage of 46.8 mm. It was observed periods with greater water deficiency (53.5 mm) in the 2018/2019 harvest for all genotypes. In short, for genotypes with 100 to 110 days of the cycle, the sowing time that showed to be the most promising to obtain higher yields, was between October 20 and November 20, for genotypes with a cycle of 120 days. This range of adaptation becomes broader, mainly because these genotypes have a longer vegetative period, being, therefore, the period of least water requirement for the crop.
